Both the stock market and oil prices have been plunging. Is this “just another cycle,” or is it something much worse? I think it is something much worse.

Back in January, I wrote a post called Oil and the Economy: Where are We Headed in 2015-16? In it, I said that persistent very low prices could be a sign that we are reaching limits of a finite world. In fact, the scenario that is playing out matches up with what I expected to happen in my January post. In that post, I said

Needless to say, stagnating wages together with rapidly rising costs of oil production leads to a mismatch between:

• The amount consumers can afford for oil

• The cost of oil, if oil price matches the cost of production

This mismatch between rising costs of oil production and stagnating wages is what has been happening. The unaffordability problem can be hidden by a rising amount of debt for a while (since adding cheap debt helps make unaffordable big items seem affordable), but this scheme cannot go on forever.

Eventually, even at near zero interest rates, the amount of debt becomes too high, relative to income. Governments become afraid of adding more debt. Young people find student loans so burdensome that they put off buying homes and cars. The economic “pump” that used to result from rising wages and rising debt slows, slowing the growth of the world economy. With slow economic growth comes low demand for commodities that are used to make homes, cars, factories, and other goods. This slow economic growth is what brings the persistent trend toward low commodity prices experienced in recent years.
